1~ Get to the rivers; rivers have current and most species of fish will not be too far away from a steady flow of it on a river system. This is the main reason I do not visit many lakes in late July and August. Rivers are a solid bet for keeping your rod bent.
2~ Weeds; oxygen levels can plummet this time of year, but if weeds are present the level of oxygen will be just fine for all species. Gills/crappies/perch as well as bass and pike will hang around the green weeds on the hottest of days. Live bait on bobbers are ket to the panfish, while weedless baits like frogs, swimjigs and Texas-Rigged plastics will work well for the larger fish.
3~ TOPWATER Baits; Bass and Pike both love coming to the surface this time of year to crash your baits. Some of my favorites include poppers, frogs, and walking baits.
4~ Early & Late; there is no other time of the year that is as important as right now to get out when the sun is coming out and fish while the sun is going down. All species will be more active and trust me, so will you!
Get out and enjoy the warm months...winter is only 3 months away!
